Hi, I have been working on a simple framework for building readers for Guile. It is called `guile-reader' and version 0.1 is available at:
http://www.laas.fr/~lcourtes/software/guile/guile-reader-0.1.tar.gz SHA1: d0a6740b4d7390e914199b0cb673355a02dd74d9 Documentation (incomplete) can be read at: http://www.laas.fr/~lcourtes/software/guile/guile-reader.html The idea is to provide an extensible, yet fast, reader for Guile. Guile already provides facilities for extending its reader (namely `read-hash-extend' and `read-enable') but these seem (i) quite limited and (ii) have a global impact (there is only one instance of `read'). Guile-reader aims to provide a way to easily define new readers, while still allowing to re-use parts of a standard Scheme reader. New reader components (called ``token readers'') may be defined either as Scheme procedures or C functions. It uses GNU Lightning (where available) to compile readers to native code, hence allowing to have performance comparable to that of Guile's built-in reader, but with improved maintainability. Guile-reader currently targets Guile 1.7 but it could trivially be ported to other versions of Guile. I'd be glad to have feedback from Guile users as to the usefulness of this approach, its shortcomings, etc. Thanks, Ludovic. _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user
